WARNING: This page is about a different car, the 2018 Hyundai Accent. However, it is still accessible from the selected car via links, so may be relevant.

The EMS can be set to the status "neutral" by tester

Ignition key (regardless of key status) is inserted and after IGN ON. If receiving the correct vehicle password from GST, Immobilizer unit can be neutralized. The neutralization of immobilizer unit is possible if DPN is same as the value inputted by GST.

In case that the immobilizer unit status is neutral, the EMS keeps the lock state. And the start is not possible by "twice ignition".

In case of changing the vehicle password, new virgin transponder must be only used. And in case of virgin key, after Learning the key of vehicle password, it can be used.

If wrong vehicle specific data have been sent to Immobilizer unit three times continuously or intermittently, the Immobilizer unit will reject the request to enter neutral mode for one hour. Disconnecting the battery or other manipulation cannot reduce this time. After connecting the battery the timer starts again for one hour.

Neutralizing Setting condition:
- In case of "Immobilizer unit status", "Learned"
- Input correct Pin code by tester
Neutralizing meaning:
